ROTARY DEEP-"WELL PUMP.

Specification of Letters Patent.

Patented Sept. 11, 1211?.

Application filed July 24, 1913. Serial No. 780,873.

To all whom it may concern:

Be it known that I, SAMUEL Lirrnur, a citizen of the United States, andresident of East Cleveland in the county of Cuyahoga and State of ()hio,have invented certain new and useful Improvements in Rotar Deep-WellPumps, of which I hereby declare the following to be a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to pumps and more particularly to pumps of therotary inclined vane type, and has for its general objects to provide anefficient pump of this type capable of forcing water or other fluidsfrom one level to a level which may be greatly elevated above the formerlevel; which will be practically continuous in operation; which will beparticularly free from liability to become clogged or obstructed, andwhich is so constructed as to operate aficiently under all ordinaryincidents of use. While capable of use in other environments, it isparticularly well adapted for forcing liquids from extremely deep wells,such as oil Wells and wells employed for irrigating purposes.

In the drawings forming part hereof,

Figure 1 represents a vertical sectional view of a well having my pumpapplied thereto, the pump beingsho'wn as operated by an electric motor;

Fig. 2 is a vertical sectional view, the parts above the pump chambercorresponding to the line 2-2 of Fig. 3.

Fig. 3 is a sectional view corresponding to the line 33 of Fig. 2;

Fig. a is a detail in perspective of the lower end of the pump shaft;

Fig. 5 is a sectional view corresponding to the line 55 of Fig. 3;

Figs. 6 and 6 are sectional details of the pump tube, the shaft beingshown in elevation; and

Fig. 7 is a view similar to Fig. [showing the pump shaft driven by awindmill.

Describing by reference characters the various parts illustrated herein,A denotes a well shaft having therein the pumping tube 13. C denotes acylindrical pump barrel connected at its upper end to the tube B bymeans of a coupling D and connected at its lower end by a coupling E toa suction tube E having a strainer E Within the tube B is the pump shaftF having at its lower end, within the barrel C,

a hub F which carries a pair of helical pumping vanes G, each less than180 in angular extent-approximately 120- whereby said vanes arecircumferentially spaced, each vane having its upper and lower .edgessubstantially horizontal, as shown at H, to cooperate with thecorresponding walls of the pump chamber.

The lower end of the pump shaft is provided with a hearing I cooperatingwith a bearing 1, there being balls J interposed between said bearings.

The lower bearing is seated on the bottom of a recess formed within theclosure K for the bottom of the pump chamber. This closure is seatedbetween the top L of the coupling E and a shoulder L formed with in thebarrel C and is provided with a pair of induction ports M spaced 180apart.

The hub F and its vanes Gr rotate in the pump chamber N provided withinthe casing C between the closure K and a vertically spaced closure 0which is seated upon the shoulder P.

The closure 0 is provided with eduction ports Q, Q, opposed to eachother and spaced about 90 each from opposed induction ports M, M, andprovided each with a gravityseating ball-valve R cooperating with aseatR and operating within a cage S.

Closely adj acent toeach port M is a vertically sliding blade T, saidblades being mounted within guideways provided within the closure 0.These blades each extend radially outwardly from the hub F intoengagement with the inner wall of the pump chamber N and each is soshaped at its lower end as to form'a substantially. fluid-tight jointwith the upper surface of each vane. These blades, as the pump shaftrotates, provide with the closures, the inner wall of the pump chamber,and the vanes, two chambers of constantly decreasing area from which theliquid sucked in from the ports M is forced into the pump tube. As thevanes rotate, they elevate the blades until the lower ends of the latterride upon the plane surfaces H at the tops of the vanes. soon as thevanes pass beneath the blades, the latter are quickly forced to thebottom of the pump chamber by means of springs :U mounted in tubularextensions V of the blade guideways.

By inspection of Fig. 3 it will be apparent that, although each vane ofless than 180 in angular extent, the blade engaging edge and theblade-discharging edge of each vane is 180 from the corresponding edgesof the other vane, so that the blades will be engaged, lifted, anddropped in like phase by each vane.

It will also be observed that the construc tion and arrangement of thevanes is such that a large chamber is provided forthe entering water atthe instant when a blade is dropped from the discharge end of its vane.This, of course, tends to a maximum pump-capacity for a pump chamber ofa given volume. However, because no intervening wall is interposedbetween the induction and eduction ports during the intervals betweenthe dropping of a blade by onevane and its engagement by the other, itwill follow that, but for the check valves R, the pump chamber would besubjected to the head of the water in the pump tube 13 during suchintervals. By the provision of the valves R, I am enabled to operate thepump continuously, at maximum capacity, and without detrimentallyaffecting the supply of the liquid to the pump chamber.

For the purpose of supporting the pump shaft within the tube B, spidersIV are provided at suitable intervals,-see Fig. 7.

IIaving described my invention, what I claim is: i

1. In a pump, the combination of a cylindrical pump chamber providedwith induction ports leading into the bottom thereof and with eductionports leading from the top thereof, a vertically extending pump tubewhereinto the eduction ports are adapted to discharge, check valves forthe eduction ports and'adapted to relieve the pump chamber from thepressure of the liquid in the tube thereabove, rotary helical vanes insaid "chamber corresponding to said eduction ports, said vanes beingcircumferentially spaced, blades slidably mounted in the top of the saidchamber adjacent to said eduction ports and adapted to be elevated bysaid vanes, means for projecting said blades downwardly to the bottom ofsaid chamber when released by said vanes, and means for rotating saidvanes.
